Fun fact of the day: did you know when you crack your back the noise is from cavitation where small cavities of gas in the joint are broken when you twist?!

I read it this morning in a Mayo Clinic pamphlet.  I crack my back every night before sleeping so I was curious what they said about it.  Is it bad for you?

They say you should avoid doing it a lot and that you are at a risk for injury if you have a herniated disk.  Hmm…I think I’ll keep cracking my back gas.

I also crack my neck and knuckles on occassion…what an obnoxious habit!…but I can’t help it.

 

Do you crack your knuckles or back?  Do you think its bad for you?!
